高光谱──遥感测绘的新机遇

Hyperspectral Remote Sensing──A New Opportunity for Surveying and Mapping

通过对高光谱遥感技术的主要优势、基本特征和地理空间信息探测潜力的分析,展示了高光谱数据在遥感测绘领域大规模应用的可能性。同时,还分析了围绕高光谱测绘应用相关的一系列问题,包括高光谱数据的测绘需求、面向测绘应用的高光谱影像分析的关键技术、高光谱遥感测绘模式以及实用化系统建立的设想等。通过对这些问题的进一步深化研究,高光谱技术就可充分与现有的遥感测绘手段有机结合,并对地理空间信息的遥感探测技术产生有力的推动。

Based on the analysis of the main advantages and basic features of the hyperspectral remote sensing technology, and the analysis of the potential of geographic information detection, this paper shows the probability of the large scale hyperspectral data application on surveying and mapping. At the same time, the authors also analyzed a series of problems on the hyperspectral application on surveying and mapping, including the requirements of the hyperspectral data, the key hyperspectral image analysis methods, the hyperspectral remote sensing application patterns, and the consideration to establish the applied surveying and mapping sys terns. Through further research on these problems, we can integrate the hyperspectral technology with the existing remote sensing methods well and effectively promote the remote sensing technology of geographic spatial information detection.
